CORE-SHELL FLUORINATED POLYMER PARTICLE FOR WEATHERPROOF COATING OF SOLAR BATTERY MODULE BACK SHEET CAPABLE OF IMPROVING WEATHERABILITY AND WET-PROOF PROPERTIES

摘要

PURPOSE: A core-shell fluorinated polymer particle for weatherproof coating of solar battery module back sheet is provided to reduce manufacturing processes of back sheets and to improve manufacturing costs.;CONSTITUTION: A core-shell fluorinated polymer particle comprises a core consisting of fluorinated polymers and a shell which introduced perfluoroalkyl group by using fluorovinylether comonomer which is represented by chemical formula 1. The chemical formula 1 is as follows: CF2=CFOCF2CF2Rf. In the chemical formula 1, Rf indicates C1-3 perfluoroalkyl or perfluoroalkoxy. The shell includes 5-30 wt% of the fluorovinylether comonomer based on the whole shell.;COPYRIGHT KIPO 2013
